latentecl Mar. 3, 1931" UNITED STATES PATENT OFFICE DOUBLE-PILE FABRICApplication mea April 13, 192s. serial no. 269,619.

My invention relates to double pile fabrics, that is to say, to fabricswhich are woven with two ground weaves, and having pile forming vwarpsextending therebetween which are subsequently cut for the purposeofproducing two separate fabrics, each having a pile face.

In my previous application for Letters Patent, filed March 27, 1928,Serial No.

1o 265,130, there is shown and described a fabric of the type aforesaid,which may be woven in a double shuttle loom. My present inventioncontemplates a fabric which is in some respects similar to the fabricthere shown,

but which, however, is more particularly adapted to be woven in a loomin which but one shuttle is thrown at each pick, and in which fabricthere will be amore substantial body of pile.

The principal object of my present invention is to provide an improveddouble pile fabric which, when cut apart, will produce two rugs orcarpets, each of the well known Tilton type. i

A further object of my invention is to provide a fabric of the typeaforesaid, in which the pile "tufts will be securely held in the groundweaves after the same are cut apart. i

Y A further object of my invention is to provide a fabric of the typeaforesaid in which therenwill be a substantial body of pile in the facethereof.

A further obj ect of my invention is to provide a fabric of the typeaforesaid, in which the dead ends of the figuring warp will be evenlydistributed in the ground weaves,

whereby the same willbe of a uniform texture, and this notwithstandingthat a certain 40 color or colors may predominate in the pile.

A further object of my invention is to provide a fabric of the typeaforesaid, whereby seamless Wilton rugs of the larger or room sizes, maybe more economically produced than heretofore.

With 'the foregoing objects in view, my invention contemplates theprovision in a double pile fabric of similar upper and lower groundweaves each having a pluralit of shots `of weft between each crossing othe binder warp, the carrying of the pile forming warp from the oneground weave to the other to form the pile, and the binding of the pilewarp in the ground weaves in such manner that the same will be securelyheld therein.

The nature and characteristic features of my invention will be morereadily understood from the following description, taken in connectionwith the accompanying drawings forming part hereof, in which:

Figure l is a longitudinal section of a double pile fabric embodying themain features of myinvention, illustrating the arrangemeit therein ofone set of figuring warps; an

Figure 2 is a similar View, illustrating the arrangement of an adjacentset of figuring warps. y

Referring to the drawings, in the particular embodiment of my inventiontherein shown, the double pile fabric comprises two similar groundweaves, the upper ground weave` consisting of pairs of binder warp l and2, and three shots of weft 3, 4 and 5, respectively, between eachcrossing of the binder warp thereof, and the lower ground weave alsoconsisting of pairs of binder warp 6 and, and three shots of weft 8, 9`and l0, respectively, between each crossing of the binder warp thereof.

It will be noted, however, that the crossing of the binder warp of thelower ground weave preferably takes place between the crossing of thebinder warp of the upper ground weave.

It should also be noted that the weft shots 3 `lie in the outer plane ofthe upper ground Weave, and the weft shots 4 and 5 liein the inner planethereof, and in like manner the weft shots 8 lie in the outer plane ofthe 90 lower ground weave, and the weft shots 9 and lie in the innerplane thereof.

For the purpose offorming the pile, the figuring warps are carried fromthe one ground weave to the other, and back again. In the drawings,there is illustrated a typical arrangement of the figuring warps whereinthe same are arranged in groups or sets of color ends, and in one groupor set (sce Fig. 1) there are three different colored figuring warps 11,12, and 13, which are primarily carried by the upper ground weave, andthree other differently colored figuring wa-rps 14, and 16, which areprimarily carried bythe lower ground weave. This arrangement willordinarily be provided in a single'dent space:

of the loom in which the fabric is woven.

In the next adjacent group or set. of color ends, (see Fig. 2) thecorresponding figuringy warps of the colors 11,-12, and 13 are primarilycarriedbythe lower ground weave, and the-three figuring warps of thecolors 14, 15'and 16in that group are primarily carried by the upperground weav Y VKVhenla figuring warp is to form the pile, thesame passesinto` the pile region from between the inner' and outer planes of theground weave where it` has been carriedas a deadend. 4 y.

At the left hand endof each figure ofthe drawings, the warp 13 is shownas making the pile, and in Fig.y 1 the same is shown as passing from the`upper ground weave, where it is :primarily carried, passing between thewefts numbered 4 and 5 of a particular shedding of the binder warp Vofthat ground weave, thence over to the other ground weave, where itpasses between the wefts numbered 9 and 10 of a particularshedding ofthat ground weave, thence between the inner and outer planes of thewefts of that ground weave, thence'returning to the original groundweave from which it was taken, passing between the wefts numbered 9 and10 of the next -shedding ofthe lower ground weave and between the weftsnumbered 4 and 5 of the same shedding ofthe upper groundv weave from.which it emerged, and repeating in like manner as long as the particularcolor is' required in the face In like-manner, in the adjacent group orset of figuring warps (see Fig. 2),v the-warp 13 which in that group v1sprimarily carried in the lower ground weave, passes between the weftsnumbered 9 andlOof a particular Vshedding of the binder warp thereof,thence over to ythe upper ground weave, where it passes between thewefts numbered of and 5 lof a particular shedding of the binder warp .lof theupper ground weave, and between the namely, 11, 111, 15 and 16,are

wefts numbered 9 and 10 of the same shedding of the lower ground Weavefrom which it emerged. Y

When the color changes, the warp which has been used in the pile formingas aforesaid is thereafter carried as a dead end between the inner andout-er planes of the weft of thel ground fabric, and another color isbrought out and in like manner carried across from the one ground fabricto the other and back again, so that the same will then appear in theface of the pile.

While, in the drawings, the warp ends 12 and 13 are the only onesillustrated as being carried over from one ground weave to the other andback again, itwill, of course, be understood that the other figuringwarps, in like manner carried over lwhenever their respective colors areused in the pile.

lt should be noted, however, that fory the best results the figuringlwarp which has been carried over to form the pilewill be finallyreturned to the ground weave from which it came, and is thereaftercarried in said ground weave as a dead end, and in this manner thedistribution of the yarn between the two ground weaves will be balancedand the texture be kept even throughout.

It will, of course, be understood that the number of pile forming Vwarpscarried by the respective upper and lower ground weaves will beconsiderably varied in practice, according to the requirements of thepattern, etc.

' It will also be apparent that, if desired, stuffer warps may be usedin addition to the figuring warps, for the purpose of giving ad ditionalbody to the ground weaves. It has not been thought necessaryv toillustratesuch stuffer-warps as the same are not essential to the weave.v Y

t will be seen that by thep-resent invention there is provided a fabricof the double pilel type, adapted to be cut apart in the usual mannerfor the purpose of formingtwo Wilton carpets or theY like, which when socut apart will produce two carpets which .will be equally desirable andofuniform texture and Y weight throughout, in 'which' thepile tufts willbesecurely bound in the ground weave,

.Y in which there will be a substantial body of pile in the facethereof, and which may be woven in widths for the production of thelarger or room size seamless rugs.
